2 A'ITORNEYS Patented Oct. 27, 1936 UNITED STATES PATENT OFFICE CONTAINER CLOSURE Henry B. Korwan, Brooklyn, N. Y.,' assignor to American Can Company, New York, N. Y., a corporation of New Jersey Application December 10, 1934, Serial No. 756,876

an outer closure for containers which is used as a protector for an inner closure during storage and shipment of the container and which is so l constructed that it serves as a reclosure and also provides successive or multiple seals-for a container before and after the removal of the inner closure.

Another object is the provision of such a mul- 15 tiple service outer cl'osure which has two container engaging walls or wall sections capable of closing a container in two different sealing positions.

Numerous other objects and advantages of the stood from the following description, which, taken in connection with the accompanying drawing,

discloses a preferredembodiment thereof.

Referring to the drawing:

Figure 1 is a perspective view of a container and closure. embodying the instant invention showing the outer cover in separated relation to the container and inner closure;

Fig. 2 is an enlarged fragmentary sectional 30 view showing the outer 'cover applied to the container over the inner closure; and

Fig. 3 is a similar view showing the outer cover utilized as a reclosure after the inner closure has been removed.

35 As a preferred embodiment of the invention the drawing discloses the invention applied to a nozzle type of container comprising a tubular body ll (Fig. 1), closed at its bottom by an end closure secured in any suitable manner as by a seam I2.

40 The upper end of the container is closed by an end closure 13, which is secured to the upper edge of the body in any suitable manner as by a seam I 4.

The top closure I 3 is provided with an open- 45 ing l5 (Fig. 1) in which a round and tapered dispensing nozzle I6 is carried, the nozzle being secured to the edge of the closure defining the opening in any suitable manner, as by soldering, welding or crimping. The upper edge of the nozzle 50 is preferably rolled outwardly in a curl ll (Fig. 2) providing a smooth top edge or closure re-- ceiving seat surrounding its open mouth. This nozzle mouth or dispensing opening is closed by an inner closure or seal it which may be frangi- 55 ble and'is preferably criniped over the curl ll,

invention will be apparent as it is better under the marginal edge of the seal being rolled around I y the curl in tight fitting engagement and extends down over the outside of the curl and terminates in a straight portion engaging the nozzle side wall under the curl.

An outer closure or auxiliary cover 25, provided for protection of the inner seal, fits over the nozzle I6 and inner seal l8 during storage and shipment of the container and is also adapted to be utilized as a reclosure when the inner 10 seal has been broken orremoved. This outer -cover comprises a paneled top wall 26 which merges into a curved wall 21 corresponding in curvature with the nozzle curl l'l. The curved wall merges into a depending flange or wall 28, having two wall sections of difierent diameter, i. e. a wall section 29 which has an inside diameter substantially equal to the outside diameter of the curl I l, and a wall section 30 which is connected with the section 29 by a curved shoulder 3| and has an inside diameter substantially equal to the outside diameter of the curl I'I, plus the thick ness of the seal I8 crimped over the curl ll. This latter wall section terminates in an outwardly rolled curl 32.

During storage and shipment of the container, the applied outer cover fits securely over the nozzle with the wall section 3|] and shoulder 3| of the flange 28 in tight frictional engagement with the outside periphery of the inner seal l8 as 3 shown in Fig. 2, thus protecting the seal against accidental opening.

When the contents of the container are to be used, the seal l8, which may be frangible or readily removable, is broken or removed from its seat or curl II. This leaves the container or the nozzle of the container with a smaller sealing seat. which would cause the ordinary outer cover whenused as a reclosure to fit too loosely on the container or nozzle. It is to prevent this condition 0 that the outer cover or closure is provided with two wall sections of difierent diameter, so that when the inner closure or seal is removed the same cover may be used as a reclosure.

When so utilized, the curved 'wall 21 of the outer cover fits over the curl ll, with the wall section 29 tightly engaging 'the outside periphery of the curl, as shown in Fig. 3. It is thus obvious that with this improved construction the outer cover will at all times fit tightly over the nozzle, protecting the sealwhen used as an inner closure and protecting the container contents when utilized as areclosure.

It will be understood that'the use of the invention is not restricted to containers having nozzles but is equally applicable to a variety of containers having dispensing openings similar to the nozzle it. v

It is thought that the invention and many of its attendant advantages will be understood from 1. A container closure construction, comprising a container having a dispensing opening defined by a closure receiving seat, a removable seal I closing said opening and engaging said seat and I an auxiliary closure covering said seal and having spaced wall sections of difierent diameters corresponding to the respective diameters of said.

seal on said seat and said seat alone, one of said wall sections being adapted to closely engage said seal on its seat and the other wall section being adapted to closely engage said seat after removal of said seal.

2. A container closure construction, comprising a container having a dispensing opening defined by a closure receiving seat, a removable inner seal closing said opening and secured to said seat, an outer closure to protect said seal and to serve as a reclosure after removal of said seal, said outer closure having a plurality of spaced portions of varying diameters for respecaoeaaea tively engaging said seal on said seat and said seat alone after said seal is removed.

3. A container closure construction, comprising a container having a dispensing opening defined by a closure receiving seat, an inner seal secured to said seat and closing said opening and seat in the absence of said seal.

4. A container having a plurality of sealing parts of difi'erent diameters and a closure adapted'to also serve as a reclosure and having parts of different diameters corresponding to the diameters of said container sealing parts, only one of said closure parts being in sealing engagement with its corresponding container sealing part at one time.

5. A container closure construction, comprising a dispensing outlet, a removable seal covering said outlet and extending over the sides thereof, and a cover for said outlet and seal, said cover having a depending flange having a large diameter section for engaging tightly over said seal when the latter is applied to said outlet and having a small diameter section for engaging tightly over said outlet when said seal has been removed therefrom.
